New sensors: Radiation, Dust/Particulates, O3, VOC's
The announcement of this project on Kickstarter has generated interest from people all over the world who are dealing with pollution in their local cities and neighborhoods. These issues are naturally widely varied, caused by any number of different sources. "Air Quality" has a very different meaning depending on where you are, and in many cases NO2 and CO alone don't tell the whole story. Hundreds of people have reached out asking for the ability to sense for specific types of pollutants, and we've been thinking about how to accommodate these important requests in a manner that is manageable for both us and the user.
To that end, we're happy to report that the outside sensor box which was initially designed to house just NO2, CO, and temp/humidity sensors has now been re-engineered into a modular plug-and-play system. We've also designed an initial set of sensor upgrade modules that can be purchased as part of this campaign, immediately:
Dust/Particulate Matter - $40 : Particle pollution ranges in size and shape and can be made up of hundreds of different chemicals and solids. Can sometimes be emitted directly from a source (factory/fire/cars), but also form out of reactions from other pollutants in the atmosphere. This is one of the most important indicators of the quality of the air you breathe.
Ozone/O3 - $25 : Ground-level ozone peaks can have immediate effects on the lungs, respiratory tract, and eyes, but also reacts with and exacerbates the effects of other pollutants, such as particulates.
Gamma and Beta Radiation - $60 : Since the Fukushima accident, efforts to create networks of citizen-gathered radiation readings have been ongoing.
Volatile Organic Compounds (VOC's)/Hydrocarbons (HC) - $25 : Describes numerous different kinds of harmful vapors from gasoline and other fuels, cleansers, paints, preservatives, to name a few.
Details of how this system works, and the design itself, will all be released as open source. More sensor options will be coming. You can add any or all of these new sensors to either of the DIY kits or the complete Air Quality Egg by simply adding the cost of the sensors you want to your pledge (we will confirm your order after the campaign ends).
Please help us spread the word about these updates to your networks! You could tweet something like this:
